1. Check and Shorten File Paths

The most frequent cause of 0x800700c1 is overly long paths. Windows 11 has a default limit of 260 characters for paths, but you can extend it or simply shorten yours.

3. Navigate to those folders and rename them to shorter versions. Avoid special characters like # or &.
4. Remove and re-add the folder to the library via Include a folder.

Pro tip: If paths are still too long, enable long path support in Windows 11:

• Open Registry Editor (search for "regedit").
• Navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\FileSystem.
• Set LongPathsEnabled to 1 (create it as a DWORD if missing).
• Restart your PC.

This simple tweak resolves the error for many users, as confirmed in recent Microsoft forums.
